This is an animated SVG featuring the Chromatic Aberration Filters available here:
<https://inkscape.org/en/~fabien.fellay/%E2%98%85chromatic-aberration-filters>
The filters have been adapted in order to obtain a red-cyan decomposition instead of the initial RGB or CMY: the horizontal offset values of the blue/yellow layer have been set to 0 user unit instead of 1.
The document also contains vectorized portions of the free and open source font 'Fira Sans'. See <https://carrois.com/typefaces/FiraSans/>.
